FlV streaming from FMS

hello sirs/madams

have written the following code:

client_nc = new NetConnection();
// Show connection status in output window
client_nc.onStatus = function(info) {
trace("Level: " + info.level + newline + "Code: " + info.code);
play_ns = new NetStream(client_nc);
myvid.attachVideo(play_ns); // Specify where to display video.
play_ns.play(“get_video.flv”); // play() uses the same name as publish() above.
// Connect to the application


play_ns.bytesLoaded outputs : 0

connection to fms is successful, but there is no output.
i want the flv to play from the fms directly into the swf

please guide …
